Moving on: The US uses 9.989 million barrels of oil per day to make gasoline (keep in mind that though a barrel contains 42 gallons of crude oil, it doesn't all go to gasoline). If we just reduced our gasoline consumption to five times that of Europe we'd knock 1.8 million barrels of oil off our daily habit.

How much oil comes from all the offshore oil wells in the Gulf of Mexico? 1.75 million barrels."
